Fog lights are a wonderful thing and are often underestimated. They can make driving in poor nighttime conditions much easier and safer thanks to the wide, flat beam of light they give off. They are located near the bottom of your front bumper, allowing a whole other area of the road to be lit. Obviously they are quite helpful in foggy conditions, but they can also help with glare, dusty roads, snow, and rain. Once you start to use them, you’ll quickly become hooked.
Fog lights work on a completely different circuit than your headlights. This means you’ll be able to turn them on and off independently so they aren’t tied to the headlight system. What they do have in common with your headlights however is the fact they use light bulbs. Unfortunately not light bulb will last the lifetime of your vehicle, which means at some point, or maybe various points, you’ll need to replace them. There is no set mileage at which this will need to be done, as it depends on how often you use them.
Here are a few signs that signal your fog light bulb has reached the end of its lifespan:
You turn on your fog lights, but nothing happens. There can be a number of things going on, but the simple answer is that your light bulbs have burnt out.
Your vehicle may provide you with a warning that lets you know your light bulb isn't working. Not all vehicles are equipped with this warning however.
The fog light bulb is found within the fog lamp assembly. These can be tricky to access, so you may prefer to have the replacement put in by a professional mechanic. They can even come to your home to do this for you.
It's also a wise idea to have the fog lights inspected when the bulb is changed. Changing both bulbs at the same time is recommended.
Your got light bulb is located within the fog light assembly. These bulbs aren’t meant to last the lifetime of your vehicle, so you will be faced with replacing them at some point. It’s always a good idea to replace both at the same time. If you’re experiencing any of the above mentioned symptoms and suspect your fog/driving light bulb is in need of replacement, get a diagnostic or book a fog/driving light bulb replacement service with a certified mechanic.
